[IA64] Stop using the deprecated __do_IRQ() code path

Mostly trivial stuff for this. The only tricky part was realizing
that the new handler_*_irq() paths do not use desc->chip->end(irq).
Not a problem for the edge case as the ia64 iosapic routine for
that was nop(). But the "level" case handled interrupt migration
there. Just use a slightly modified version of the "end" routine
as "unmask" for the level triggered case.
